Material Information

When the surface of aluminium metal is exposed to air, a protective oxide coating forms almost instantaneously which gives excellent corrosion resistance. This oxide layer can be further enhanced with surface treatments such as anodising. It is widely recognised that aluminium is the best material for making windows and doors from, when they are to be installed in marine environments.

The recyclability of aluminium is unparalleled. When recycled there is no degradation in properties when recycled aluminium is compared to virgin aluminium.


To enhance the look and add the finishing touches to your Endurance door, there is a wide choice of door hardware and security options to choose from.

Colours Options: Gold, Graphite, Bronze, White, Antique Black, Black, Chrome.
